Title: Frequency converter
Inventor: IWAI KEISUKE
IPC: H03D9/06
Filed: 1991-04-02
Abstract: PURPOSE:To improve the frequency converter by blocking the application of a local oscillation signal to an RF input. CONSTITUTION:An RF signal passing through an RF signal band pass filter 1 is fed to a mixer 3 via an RF signal coupling line 2a and a local oscillation signal Lo is fed to the mixer 3 via an Lo signal band pass filter 4. Since the length from an input terminal of the RF signal S to the said mixer 3 till a short-circuit end of an image short stub 2b is selected to be a half wavelength with respect to the local oscillation signal Lo and to be almost a wavelength with respect to an image signal, the said input terminal of the mixer 3 is short- circuited with respect to both the signals and both the signals are reflected thereto. Moreover, the length from the said input terminal till an open end of the RF signal coupling line 2a is selected to be a 1/4 wavelength of the said local oscillation signal Lo and the signal Lo is reflected thereto similarly as above. Then the RF signal S is mixed efficiently with the local oscillation signal Lo resulting in a prescribed intermediate frequency signal IF, which is outputted from a low pass filter 5.

Title: Resetting circuit
Inventor: FUJITA KOUICHI
IPC: G06F1/00
Filed: 1979-06-04
Abstract: PURPOSE: To make it possible to reset FF securely without reference to the frequency of a microprocessor by letting a counter count a reset period digitally.  
     CONSTITUTION: Being designed asymmetrically, FF5 is set to "1" at the rise of an electric power voltage and by its output, the address of program counter 4 is forcibly specified. On detecting counter 4 showing the specific address, address detecting circuit 6 actuates counter 7, which is cleared at the rise of the power voltage. As a result, clocks of a microprocessor are counted from zero and when counter 7 overflows, its signal is transferred to FF5, which is reset and counter 4 deviates from the specific address. Namely, the reset period is digitally counted.

Title: Carriage drive mechanism for floppy disk drive
Inventor: NAKAMURA NORIO
IPC: G11B21/02
Filed: 1986-03-31
Abstract: PURPOSE:To make the stop position of a carriage accurate with respect to repetitive accuracy in both directions by converting the drive of a stepping motor into rectilinear motion to move the carriage thereby facilitating assembling. CONSTITUTION:A lead screw coupled directly is driven by the drive of the stepping motor 17. A slot 161 is driven by the drive of the lead screw 16 and a ball bearing 15 arranged on the slot 161 is moved while being traced to the slot 161. In this case, the ball bearing 15 keeps the relative position to the lead screw 16 by a plate spring 19. Thus, the bearing is not moved in the rotation direction of the lead screw but moved in the axial direction only. That is, the ball bearing 15 is moved in the axial direction of the lead screw 16 by the drive of the lead screw 16 along the slot 161 and moves straight forward. Then the rotation drive of the stepping motor 17 is converted into the rectilinear motion and the plate spring 19 is moved on the lead screw 16.

Abstract: PURPOSE:To improve sealing performance by as utilizing only the merits of the gasket and the sealant in such a way applying a sealant on the end surface along the periphery of a gasket, when the driving system of an engine and the transmission of a car are sealed together. CONSTITUTION:Sealant 2 is applied on the end surface along the periphery of a paper gasket 1, and tightened. Humidity-hardening type silicone is used as the sealant. At the same time in tightening, the sealant 2 is extruded around the gasket, also stuck to the aluminium on the flange 3 surface, and filled into narrow gap formed by the flange 3, its counterpart 5, and screw 4, which hold the gasket 1 therebetween.
